PURPOSE:To facilitate classification of mode, in a watch which drives hands by two electrical-mechanical converters, by driving the first electrical-mechanical converter and then the second electrical-mechanical converter. CONSTITUTION:Frequency of a signal emitted from a time reference signal source 9 is divided to be turned into a signal of 1Hz and put into an electrical-mechanical converter 20, and the second hand 5 is moved by one second. And, an electricalmechanical converter 21 is driven every 20sec, and thereby the minute hand 6 is moved. When a switch S13 is operated to make it possible to indicate an alarmsounding time on an analog indicating mechanism 2, differences among an alarm counting circuit, a second counting circuit and a minute-and-hour counting circuit 14 are operated 18. And, the second hand 5 is driven to the position of 0sec at first, and when this is completed, a remaining pulse generating circuit 30 puts out a detection signal, and this time, the minute hand 6 and the hour hand 7 are quickly turned to the alarm-sounding time. |
